Abstract

A parking assist device (1) includes a camera (3) for capturing an image of an exterior of a vehicle, and a monitor (4) for displaying the captured image, and sets a target parking position by moving a target parking frame (11) displayed on a screen of the monitor (4). A default position of the target parking frame (11) is determined based on a target parking position (P2) which is a relative position with respect to a parking preparation position (P1). The target parking position (P2) is estimated based on a running state of the vehicle until the vehicle reaches the parking preparation position (P1).
